DEVICE FOR GENERATING LIGHT WITH VARYING COLOUR Russian patent published in 2011 - IPC H05B33/08 H04N1/60 

FIELD: physics.

SUBSTANCE: illumination system (100) comprises: a set (14) of lamps; a controller (115); a user input device (19); memory (120) which determines discrete colour points containing an ID table (121) of hue, an ID tale (122) of saturation, an ID table (123) of brightness and boundary memory (124) which determines the boundary of the colour space. Based on data (x1, x2, x3) received from the user input device and information in the memory, the controller generates colour control signals (ξ1, ξ2, ξ3) for the set of lamps. The controller compares user input data with information in the boundary memory. If the controller detects that the said point lies beyond the boundaries of the colour space, the controller calculates the replacement point on the boundary of the colour space which was determined in the boundary memory (124), and generates is control signals based on the replacement point.

EFFECT: reduced volume of memory space required.
